CB550 F2 Clock Cushions

[Neilw]

I'm trying to source some replacement clock cushions for my 1978 CB550 F2 UK.  However, the correct part number - 37235323700 is just too big for my clocks.

A previous owner may have fitted smaller clocks, bracket and, baskets and cushions from another bike, as they all fit together perfectly. I don't want the expense of changing everything, so any idea which CB model has smaller clocks than the CB550, as that is my only guess, so i can get cushions to fit.

BTW, the mileage on the MOT's matches the clock's mileage, so if they were swapped, they were done a while ago.

A lot of the 250, 350, 460 twins used the same casings.

I have stock of OEM clock cushions for the 400 and 500, also the 550F but you've already said the 550 cushions  are too big for your clocks.

Brilliant, i'll order some cb400 f ones.

I’d imagine that as the 550f has a 19” front wheel and the 400f has an 18” front wheel the speedo will not read true. Plus the F2 got blue faced clocks like the 550K3, the F1 got green faced clocks just for info. So the smaller clocks fitted would imo look out of place and reduce its value if you came to resell. Personally I’d find and fit some genuine F2 clocks, you can find them cheaper sometimes.

Thats a good point, I hadn't thought of that.

The joys of the bike just keep giving :-)

I'm finding it a bit of a challenge to find the correct clocks on Ebay. There are lots of KPH clocks, but not so many MPH clocks with the correct faces.

Just a thought, if I got a KPH clock and then put a correct mph replacement face on it, that would work, wouldn't it?, as long as it was off one of the compatible bikes? Or am I missing something?

You can put a MPH face on a km/h speedo but the distace counters will still read in kms as the counters are gear driven from the cable drive spindle.

Good point, I knew there'd be something. Thank you.
